A NEW PHILIPPINE STENOCRANUS (DELPHACIDiE, 

 HOMOPTERA) 



By F. Muir 

 Of the Hawaiian Sugar Planters' Experiment Station, Honolulu 



TWO TEXT FIGURES 



Stenocranus seminigrifrons sp. nov. Fig. 2. 



Male.— Macropterous; length, 2.7 millimeters; tegmen, 3.3. 

 Length of vertex, pronotum, and mesonotum 1.6 times the width 

 of head including eyes; length of vertex 1.5 times the width 

 at base, base slightly broader than apex; length of face 2.2 

 times the width, sides straight, slightly diverging apically, apex 



broader than base. Antennae reaching slightly beyond base of 

 clypeus, first segment longer than broad, second segment 1.6 

 times the length of first. Lateral pronotal carinas straight, di- 

 verging, not quite reaching hind margin. Hind basitarsus 

 slightly longer than the other two together, spur about as long 

 as basitarsus, thin, with many small teeth on margin. 



The genitalia of this species differ from those of S. mgrifrons 

 Muir in having the anal spines much larger and diverging, with 

 a small spine toward the apex; the *deagus is curved about 

 one-third from apex into a crook, forming nearly a semicircle, 

 and the genital styles are longer and slender. The two species 

 are closely related.
